A device for supporting weak bony structures includes a body (11) having fir st and second ends (12, 13) configured for contacting adjacent bony structures. The body (11) has a wall with a number of openings (35), and the wall define s a hollow chamber (16) for receiving bone growth inducing material. The devic e includes an end cap (100) for placement in the hollow chamber (16) adjacetn one of the ends of the body (11). The end cap (100) has opposite upper and lower surfaces (116, 117), and includes a plurality of arms (106) extending from a central ring (105). Each of the arms having a first end (106a) connected with the ring and an opposite second end (106b) including an outer surface (110). Each of the outer surfaces (110) are positionable adjacent th e inner surface of the wall of the body (11) when the end cap (100) is inserte d into the hollow chamber (16). Each arm (106) can also include a projection (112) that extends at least partially into a wall opening (35). |
